organic impurities of aggregates

PROPERTIES OF AGGREGATES FOR CONCRETE , organic impurities of aggregates ,The aggregate is usually washed to remove any dust, silt, clay, organic matter, or other impurities that would interfere with the bonding reaction with the cement paste It is then separated into various sizes by passing the material through a series of screens with different size openingsOrganic Impurities - Special Tests - Aggregates | ,Organic Impurities Detects the presence of organic compounds in fine aggregate sampl A positive test result indicates need for further tests prior to using source material in cement or mortar formulations.
